I have this method:
+ (MHTwitterParser*)createParser:(NSString*)format {
if ([format compare:@"json"] == NSOrderedSame) {
return [[MHJsonTwitterParser alloc] init];
}
[NSException raise:@"Unknown format" format:@"Unknown format of parser"];
}
Compiler complains that:
Control may reach end of non-void function
It is just a warning, but it does not matter.
Obvious fix for that is to add for example return nil;
after the [NSException raise: ...
.
However, I think it is not needed (and is even misleading for readers), because the exception is thrown, so it is not true that "Control may reach end of non-void function". Or am I missing something ...? Is it only compiler imperfection or there is some considerable reason for this?
The compiler is Apple LLVM compiler 3.1
Replacing [exception raise];
with @throw exception;
is functionally the same thing and will prevent the warning (see: Throwing Exceptions).
